Valve Backs Zink Work

  • Mike Blumenkrantz: Don’t Call It A Comeback

    I guess I never left, really, since I’ve been vicariously living the life of someone who still writes zink patches through reviewing and discussing some great community efforts that are ongoing. But now I’m back living that life of someone who writes zink patches. Valve has generously agreed to sponsor my work on graphics-related projects. For the time being, that work happens to be zink.

  • Valve Now Funding Blumenkrantz - Zink OpenGL-On-Vulkan To Continue

    Longtime open-source developer Mike Blumenkrantz who has been an Enlightenment developer for many years and was working for Samsung's Open-Source Group prior to its demise jumped into the open-source Linux graphics world this year. While being unemployed he began hacking on the Zink Gallium3D code that allows generic OpenGL acceleration over the Vulkan API. He quickly got the code to the point of OpenGL 4.6 support and quite compelling performance compared to where Zink was at earlier this year. Now it turns out he will continue with his Linux graphics adventures thanks to funding from Valve. Mike Blumenkrantz shared today that Valve is going to be sponsoring his graphics-related work moving forward. At least for now, that Linux graphics work is still on the matter of Zink.

On Safety Razors and Technology

Think Windows on one side, vs Linux (and the BSDs) on the other (with macOS initially being in the middle and increasingly swaying to becoming even more constraining than Windows). Think proprietary gaming consoles and mobile IAP-chasing games, vs game platforms that encourage participation like TIC-80 and LÖVE. Think US-centric proprietary social networks (Facebook, Twitter) and services (Dropbox, Google Suite) vs distributed social networks (Mastodon, Pleroma, Diaspora etc.) and self-hosted services (Nextcloud, Cryptpad etc.). What are most people sacrificing to the altar of promised convenience? Literally both time and money: our attention, higher costs; also our autonomy (you’re locked in) and our privacy (… so platform owners can mine your attention and monetize what they observe of your behavior). If you believe in capitalism, this is bad news. If you don’t it’s even worse. [...] But in other jurisdictions like the US, regulation might be a long time coming, except maybe in California (plus the companies we’re trying to unshackle users from are mostly US-based). So a lot of the solution has to be bottom up. We simply need to lower barriers to entry, both actual and perceived, to using the platforms we’re championing. Some involve compromises (e.g. Flatpak is a great way to abstract away the differences between Linux distributions, to the point that it’s easier to install proprietary apps, including Steam – which improves the availability of games on Linux despite, yes, being proprietary). Some involve corporate backing (e.g. Fedora on Lenovo laptops). A lot would involve being more welcoming to newcomers, and bridging the actual usability gaps there are. It’s hard enough to overcome incumbency and the network effect. Let’s not make it harder for ourselves. Read more

Mobile/Desktop Convergence

Mobile/Desktop convergence is something that Purism had planned and has been developing since the launch of the Librem 5. It all started with the amazing work that Adrien initiated with the libhandy library, that let the default Librem 5 applications be adapted from the exact same applications running on the laptops. Now the Librem 5 team is moving a step further by letting the Librem 5 being used as a real desktop computer by simply plugging it into an external monitor, keyboard and mouse through a single USB hub. The feature is still under active development at the time of writing this article, but the different components are starting to come together and it is already pretty functional. Read more

  • Linux Fu: VPN For Free With SSH | Hackaday

    If you see a lot of banner ads on certain websites, you know that without a Virtual Private Network (VPN), hackers will quickly ravage your computer and burn down your house. Well, that seems to be what they imply. In reality, though, there are two main reasons you might want a VPN connection. You can pay for a service, of course, but if you have ssh access to a computer somewhere on the public Internet, you can set up your own VPN service for no additional cost. The basic idea is that you connect to a remote computer on another network and it makes it look like all your network traffic is local to that network. The first case for this is to sidestep or enhance security. For example, you might want to print to a network printer without exposing that printer to the public Internet. While you are at the coffee shop you can VPN to your network and print just like you were a meter away from the printer at your desk. Your traffic on the shop’s WiFi will also be encrypted.

  • YANUB: yet another (nearly) useless blog: QSoas tips and tricks: using meta-data, first level

    By essence, QSoas works with \(y = f(x)\) datasets. However, in practice, when working with experimental data (or data generated from simulations), one has often more than one experimental parameter (\(x\)). For instance, one could record series of spectra (\(A = f(\lambda)\)) for different pH values, so that the absorbance is in fact a function of both the pH and \(\lambda\). QSoas has different ways to deal with such situations, and we'll describe one today, using meta-data. [...] QSoas is a powerful open source data analysis program that focuses on flexibility and powerful fitting capacities. It is released under the GNU General Public License. It is described in Fourmond, Anal. Chem., 2016, 88 (10), pp 5050–5052. Current version is 2.2. You can download its source code there (or clone from the GitHub repository) and compile it yourself, or buy precompiled versions for MacOS and Windows there.

  • How to add a WordPress user sign up - Anto Online

    Adding an external user sign up page on a website allows users to register for different roles.
